Description

この発明は、工具選択の機構を改良した旋盤に関する。   The present invention relates to a lathe having an improved tool selection mechanism.

従来からある旋盤の一つの形式は、固定の主軸と、X,Z軸方向に移動する刃物台とを備える。刃物台は、Z軸回りに旋回するタレット式したものが多い。タレットは、一般的には多角形のドラム状に形成され、外周の複数箇所に各工具を取付ける。この他に、タレットを環状としてその中空部の中心に向くように工具を取付けたものも提案されている(例えば特許文献1)。他の形式として、刃物台に櫛歯状に工具を並べて取付けるようにしたものがある。
特開2002−337010号公報
One type of conventional lathe includes a fixed spindle and a tool post that moves in the X and Z axis directions. Many of the turrets are turrets that rotate around the Z axis. The turret is generally formed in a polygonal drum shape, and each tool is attached to a plurality of locations on the outer periphery. In addition to this, a tool in which a turret is annular and a tool is attached so as to face the center of the hollow portion has been proposed (for example, Patent Document 1). As another type, there is a tool in which tools are arranged side by side in a comb shape on the tool post.
JP 2002-337010 A

従来のタレット式の旋盤は、タレットを旋回させて工具割出しを行うものであるため、工具選択の割出時間が長くなる。すなわち、タレットを旋回させるものでは、加工時にタレットが旋回方向に微妙に移動して加工精度が低下することを防止するため、旋回割出後にクランプを行うようにしている。そのため、旋回割出には、アンクランプ、旋回、クランプの各過程が必要となり、割出時間が長くなる。特許文献1に示される旋盤は、工具を取付ける方向が中空部の中心側であることで一般のタレット旋盤とは異なるが、タレットを旋回して工具割出を行うことについては一般的なタレット旋盤と同様である。   Since the conventional turret type lathe performs tool indexing by turning the turret, indexing time for tool selection becomes long. That is, in the case of turning the turret, in order to prevent the turret from moving delicately in the turning direction during processing and lowering the processing accuracy, clamping is performed after turning indexing. Therefore, turning indexing requires unclamping, turning, and clamping processes, and the indexing time becomes long. The lathe disclosed in Patent Document 1 differs from a general turret lathe in that the direction in which the tool is attached is on the center side of the hollow portion. It is the same.

従来の櫛歯タイプの旋盤は、刃物台の旋回割出時間の問題はないが、工具を一列に直線状に配列するものであるため、1台の旋盤で多数の工具を持つには、工具配列方向に刃物台が長くなり過ぎ、現実的でない。
また、従来の旋盤は、いずれも切粉の効率的な排出処理が難しいという課題がある。
The conventional comb-type lathe does not have a problem of the indexing time of the tool post, but the tools are arranged in a line in a straight line. The tool post becomes too long in the arrangement direction, which is not realistic.
Moreover, all the conventional lathes have a problem that it is difficult to efficiently discharge chips.

この発明の目的は、工具の割出時間が短縮され、加工時間が短縮できる旋盤を提供することである。
この発明の他の目的は、切粉の排出性を向上させることである。
An object of the present invention is to provide a lathe capable of shortening the indexing time of the tool and shortening the machining time.
Another object of the present invention is to improve the dischargeability of chips.

この発明の旋盤は、中央に中空部を有する環状に形成されて前記中空部の中心軸に刃先が向くように複数の工具を取付可能で上記中心軸回りの回転が不能な刃物台と、主軸軸心が前記中空部の中心軸と平行でありワークを支持する主軸とを備え、前記刃物台および主軸のいずれかを主軸軸心と平行な方向に移動させてワークを前記中空部に進入自在とすると共に、前記刃物台または主軸を前記主軸軸心に垂直な面内で移動させて前記複数の工具のうちの任意の1つの工具を選択してワークに加工を可能とした刃物台・主軸相対移動手段を設け、かつ前記中空部に、切粉排出用の負圧吸引装置のダクトの一端を連通させてこのダクトの前記一端を前記刃物台の背面側に取付けたものである。
この構成の旋盤によると、刃物台・主軸相対移動手段により、刃物台および主軸のいずれかを主軸軸心と平行な方向に移動させてワークを前記中空部に進入させ、この状態で、刃物台または主軸を前記主軸軸心に垂直な面内で移動させることにより、刃物台の複数の工具のうちの任意の1つの工具を選択し、ワークの加工を行うことができる。このため、刃物台を旋回させずに工具割出が行え、工具の割出時間が短縮される。これにより加工時間が短くなる。また、工具は刃物台に放射状に配置されるため、工具を直線状に並べる櫛歯状の旋盤と異なり、多数の工具を取付けるものとしても、刃物台の幅が大きくなり過ぎるという問題がない。しかも、刃物台が旋回しない形式であるため、負圧吸引装置のダクトの端部を取付け易く、旋盤における課題であった切粉の排出性を向上させることができる。
Lathe of the present invention, the attachable and said central axis of rotation is non tool rest a plurality of tools so as to face the cutting edge to the center of an annular shape to have a hollow portion by the hollow portion shaft in the center, A spindle having a spindle axis parallel to the central axis of the hollow part and supporting the workpiece, and moving either the tool post or the spindle in a direction parallel to the spindle axis to enter the workpiece into the hollow part A tool post that can be freely processed, and the tool post or the spindle is moved in a plane perpendicular to the spindle axis so that any one of the plurality of tools can be selected and processed into a workpiece. only set the spindle relative movement means, and the hollow portion is made to communicate with one end of the duct of negative pressure suction device for chip discharge those attached to the one end of the duct to the rear side of the tool rest.
According to the lathe of this configuration, the tool post / spindle relative movement means moves either the tool post or the spindle in a direction parallel to the spindle axis to allow the workpiece to enter the hollow portion. Alternatively, by moving the spindle in a plane perpendicular to the spindle axis, any one of a plurality of tools on the tool post can be selected and the workpiece can be machined. For this reason, tool indexing can be performed without turning the tool post, and the tool indexing time is shortened. This shortens the processing time. Also, the tool to be arranged radially on the tool rest, unlike the comb-shaped lathe arranging the tool in a straight line, even as attaching a large number of tools, a problem that the width of the tool rest is too large is not Na . In addition, since the tool post does not turn, it is easy to attach the end of the duct of the negative pressure suction device, and it is possible to improve the dischargeability of chips, which is a problem in a lathe.

この発明における他の旋盤は、上記構成において、刃物台を固定設置して主軸だけを移動させるようにしたものである。すなわち、この旋盤は、中央に中空部を有する環状に形成されて前記中空部の中心軸に刃先が向くように複数の工具を取付可能で固定設置された刃物台と、主軸軸心が前記中空部の中心軸と平行でありワークを支持する主軸とを備え、前記主軸を主軸軸心と平行な方向に移動させてワークを前記中空部に進入自在にすると共に、主軸軸心と垂直な面内で移動させて前記複数の工具のうちの任意の1つの工具を選択してワークに加工を可能とした刃物台・主軸相対移動手段を設け、かつ前記中空部に、切粉排出用の負圧吸引装置のダクトの一端を連通させてこのダクトの前記一端を前記刃物台の背面側に取付けたものである。
この構成の場合、刃物台・主軸相対移動手段により、主軸を主軸軸心と平行な方向に移動させてワークを前記中空部に進入させ、この状態で、主軸を主軸軸心に垂直な面内で移動させることにより、刃物台の複数の工具のうちの任意の1つの工具を選択し、ワークの加工を行うことができる。この構成の場合も、刃物台を旋回させずに工具割出が行え、工具の割出時間が短縮される。これにより加工時間が短くなる。また、この構成の場合、工具を中空軸心に向かって取り付けることにより大きくなってしまう刃物台を移動させるのではなく、主軸を移動させるようにしたので、より高速加工が可能となる。しかも、刃物台が旋回しない形式であるため、負圧吸引装置のダクトの端部を取付け易く、旋盤における課題であった切粉の排出性を向上させることができる。
Another lathe according to the present invention has the above-described configuration in which the tool post is fixedly installed and only the main spindle is moved. That is, the lathe, the tool rest which a plurality of tools as an annular shape to have a hollow portion facing the cutting edge to the central axis of the hollow portion is fixedly installed to be capable of being attached to a central spindle axis is the A main shaft that is parallel to the central axis of the hollow portion and supports the work, and moves the main shaft in a direction parallel to the main shaft axis so that the work can enter the hollow portion and is perpendicular to the main shaft axis. only set possible with the tool rest, the spindle relative movement unit processing any select one of the tool to the work of the tool in moved in the plurality in terms, and in the hollow portion, a chip discharge One end of the duct of the negative pressure suction device is communicated, and the one end of the duct is attached to the back side of the tool post .
In this configuration, the tool post is moved in a direction parallel to the spindle axis by the tool post / spindle relative movement means, and the work is caused to enter the hollow portion, and in this state, the spindle is in a plane perpendicular to the spindle axis. It is possible to select an arbitrary one of the plurality of tools on the tool post and to process the workpiece by moving the tool. Also in this configuration, tool indexing can be performed without turning the tool post, and the tool indexing time is shortened. This shortens the processing time. Also, in this configuration, rather than moving the tool rest which increases by attaching toward the tool to the hollow axis, since to move the spindle, that Do enables faster processing. In addition, since the tool post does not turn, it is easy to attach the end of the duct of the negative pressure suction device, and it is possible to improve the dischargeability of chips, which is a problem in a lathe.

この発明の旋盤は、中央に中空部を有する環状に形成されて前記中空部の中心軸に刃先が向くように複数の工具を取付けた回転不能な刃物台と、主軸軸心が前記中空部の中心軸と平行でありワークを支持する主軸とを備え、前記刃物台および主軸のいずれかを主軸軸心と平行な方向に移動させてワークを前記中空部に進入自在とすると共に、前記刃物台または主軸を前記主軸軸心に垂直な面内で移動させて前記複数の工具のうちの任意の1つの工具を選択してワークに加工を可能とした刃物台・主軸相対移動手段を設けたものであるため、工具の割出時間が短縮され、加工時間が短縮できる。また、前記中空部に、切粉排出用の負圧吸引装置のダクトの一端を連通させたため、切粉の排出性が向上する。
この発明の他の旋盤は、中央に中空部を有する環状に形成されて前記中空部の中心軸に刃先が向くように複数の工具を取付可能で固定設置された刃物台と、主軸軸心が前記中空部の中心軸と平行でありワークを支持する主軸とを備え、前記主軸を主軸軸心と平行な方向に移動させてワークを前記中空部に進入自在にすると共に、主軸軸心と垂直な面内で移動させて前記複数の工具のうちの任意の1つの工具を選択してワークに加工を可能とした刃物台・主軸相対移動手段を設けたものであるため、工具の割出時間が短縮され、加工時間が短縮できる。また、この構成の場合、工具を中空軸心に向かって取り付けることにより大きくなってしまう刃物台を移動させるのではなく、主軸を移動させるようにしたので、より高速加工が可能となる。また、前記中空部に、切粉排出用の負圧吸引装置のダクトの一端を連通させたため、切粉の排出性が向上する。

この発明の一実施形態を図1および図2と共に説明する。この旋盤は、ベッド1上に刃物台2を固定設置し、主軸3を、刃物台・主軸相対移動手段4によって移動可能に設置したものである。主軸3は、ワークWを支持するものであり、ワークWを把持する主軸チャック3aを有している。   An embodiment of the present invention will be described with reference to FIGS.

The tool post 2 has a hollow portion 5 in the center, and a plurality of tools 6 in various directions can be attached radially so that the cutting edge faces the central axis O1 of the hollow portion 5. The tool post 2 is formed in an annular shape and has tool stations S at a plurality of locations in the circumferential direction. A tool 6 with the cutting edge facing the central axis O1 is attached to any plural or all of the tool stations S. Tools (not shown) facing in other directions may be attached to the remaining tool stations S.
The tool 6 with the cutting edge facing the central axis O1 is for outer diameter processing, for example. The figure shows a state in which the outer diameter machining tools 6 are attached to four of the eight tool stations S. Although not shown in the drawings, the remaining tool stations S are attached with an inner diameter machining tool, an end face machining tool, a drill, a milling head, and other rotary tools. In the case of a tool such as an inner diameter machining, an end face machining, and a rotary tool, for example, the tool is installed so as to extend toward the main shaft 3 in parallel with the central axis O1 of the hollow portion 5.

刃物台・主軸相対移動手段4は、主軸3を、主軸軸心O2と平行な方向(Z軸方向)に移動させてワークWを前記中空部5に進入自在にすると共に、主軸軸心O2と垂直な面(X,Y平面)内で移動させて前記複数の工具6のうちの任意の1つの工具6を選択し、その工具6によるワークWの加工を可能とする手段である。
刃物台・主軸相対移動手段4は、前後移動台7、上下移動台8、左右移動台9と、これら各移動台7〜9の進退駆動装置(図示せず)とで構成される。左右移動台9は、主軸3が回転自在に設置されたものであり、主軸台となる。左右移動台9に主軸モータ(図示せず)が設置されている。
The tool post / spindle relative moving means 4 moves the spindle 3 in a direction parallel to the spindle axis O2 (Z-axis direction) to allow the workpiece W to enter the hollow portion 5 and to move the spindle axis O2. It is a means for selecting an arbitrary one of the plurality of tools 6 by moving in a vertical plane (X, Y plane) and enabling the workpiece W to be machined by the tool 6.
The tool post / spindle relative movement means 4 includes a front / rear moving table 7, a vertical moving table 8, a left / right moving table 9, and an advancing / retreating drive device (not shown) for each of these moving tables 7-9. The left / right moving base 9 is a main spindle 3 in which the main spindle 3 is rotatably installed. A spindle motor (not shown) is installed on the left / right moving base 9.

前後移動台7は、ベッド1上の主軸ベース10に、直線案内手段11を介して主軸平行方向(Z軸方向)に移動自在に設置され、サーボモータおよびボールねじ等からなる進退駆動機構(図示せず)によって主軸平行方向Zに進退させられる。

The back-and-forth moving table 7 is installed on the main shaft base 10 on the bed 1 so as to be movable in the main shaft parallel direction (Z-axis direction) via the linear guide means 11, and is moved forward and backward by a servo motor and a ball screw. (Not shown) is advanced and retracted in the main axis parallel direction Z.

The linear guide means 12 is provided on a support column 7 a provided on the vertical movement table 7.
The left-right moving base 9 is installed so as to be movable in the left-right direction (X-axis direction) via a linear guide means 13 provided on the up-and-down moving base 8, and a forward / backward drive mechanism (not shown) including a servo motor and a ball screw. ) To move forward and backward in the left-right direction X.

上記各直線案内手段11,12,13は、滑り案内を行うものであっても、また直動転がり軸受であっても良い。なお、上記前後移動台7、上下移動台8、および左右移動台9により、可動主軸支持台16が構成される。   Each of the linear guide means 11, 12, and 13 may perform a sliding guide or may be a linear motion rolling bearing. Note that the movable spindle support base 16 is constituted by the front / rear moving base 7, the vertical moving base 8, and the left / right moving base 9.

刃物台2の背面側には、切粉排出用の負圧吸引装置14のダクト15の一端を、連通状態に取付けてある。負圧吸引装置14は、吸引式のブロワー(図示せず)等と回収ボックス14aとで構成される。   One end of the duct 15 of the negative pressure suction device 14 for discharging chips is attached to the back side of the tool post 2 in a communicating state. The negative pressure suction device 14 includes a suction blower (not shown) and the like and a collection box 14a.

上記構成の動作を説明する。刃物台・主軸相対移動手段4における前後移動台7の前進により、主軸3を主軸軸心O2と平行な方向に移動させてワークWを刃物台2の中空部5に進入させる。この状態で、上下移動台8の上下(Y軸方向)移動や、左右移動台9の左右(X軸方向)移動によって、主軸3を主軸軸心O2に垂直な面内で、移動させることにより、刃物台2の複数の工具6のうちの任意の1つの工具6を選択する。すなわち、その選択される工具6に、図2のようにワークWを近づける。図2は、図の左側の水平位置にある工具61 を選択した状態である。 The operation of the above configuration will be described. The forward / backward movement of the turret / spindle relative movement means 4 causes the spindle 3 to move in a direction parallel to the spindle axis O <b> 2 so that the workpiece W enters the hollow portion 5 of the turret 2. In this state, by moving the spindle 3 in a plane perpendicular to the spindle axis O2 by moving the vertical moving table 8 up and down (Y-axis direction) and moving the left and right moving table 9 left and right (X-axis direction). , One arbitrary tool 6 among the plurality of tools 6 of the tool post 2 is selected. That is, the workpiece W is brought close to the selected tool 6 as shown in FIG. Figure 2 is a state in which selected the tool 61 in a horizontal position on the left side of FIG.

このように工具6を選択し、工具6の延びる方向に、主軸台となる左右移動台9を移動させることにより、ワークWに対する切り込み方向の工具6の移動が行え、ワークWの外径加工を行うことができる。ワークWに対する送り方向の工具6の移動は、前後移動台7の移動により行う。
図2中に鎖線で示すような斜め方向の工具64 を選択した場合は、図1の左右移動台9と上下移動台8の複合動作でワークWの半径方向の切り込み動作を行うことになる。
In this way, by selecting the tool 6 and moving the left / right moving base 9 as the headstock in the extending direction of the tool 6, the tool 6 can be moved in the cutting direction with respect to the work W, and the outer diameter machining of the work W can be performed. It can be carried out. The movement of the tool 6 in the feed direction with respect to the workpiece W is performed by the movement of the front / rear moving table 7.
If you choose a diagonal direction of the tool 6 4 as shown by a chain line in FIG. 2 will make a radial incision operation of the workpiece W in the combined operation of the right and left moving table 9 and vertically moving base 8 in Figure 1 .

このように、刃物台2を旋回させずに、主軸3の移動によって工具割出が行えるため、工具6の割出時間が短縮される。これにより加工時間が短くなる。また、刃物台2は、中央に中空部5を有しこの中空部5に刃先が向くように複数の工具6を取付けるものであるため、従来の櫛歯型の刃物台に比べ、多数の工具6を取付けるようにしても左右の幅寸法が小さなもので済む。   Thus, the tool indexing time can be reduced by moving the spindle 3 without turning the tool post 2, so that the indexing time of the tool 6 is shortened. This shortens the processing time. In addition, the tool post 2 has a hollow portion 5 in the center, and a plurality of tools 6 are attached so that the cutting edge faces the hollow portion 5. Even if 6 is attached, the left and right width dimensions may be small.

加工によって生じた切粉は、負圧吸引装置14によりダクト15を介して吸引され、その回収ボックス14aに回収される。刃物台2は中央に中空部5を有するものであり、ダクト15はこの中空部5に連通するように取付けてあるため、効率的な吸引が行える。また、刃物台2は回転しないため、中空部5とダクト15の端部とを連通させるについて、相互の回転を許容する手段を設ける必要がなく、接続が容易に行える。   The chips generated by the processing are sucked through the duct 15 by the negative pressure suction device 14 and collected in the collection box 14a. Since the tool post 2 has a hollow portion 5 in the center, and the duct 15 is attached so as to communicate with the hollow portion 5, efficient suction can be performed. In addition, since the tool post 2 does not rotate, it is not necessary to provide means for allowing mutual rotation when the hollow portion 5 and the end of the duct 15 are communicated with each other, and the connection can be easily performed.

なお、上記実施形態では、刃物台2は円環状としたが、刃物台2は、矩形等の多角形の環状であっても良く、また中空部が円形で外周部が角形であっても良い。また、刃物台2は、周方向に複数個に分割されていても良く、その分割刃物台の相互間に隙間があっても良い。
可動主軸支持台16を構成する前後移動台7、上下移動台8、および左右移動台9のベッド1に対する設置順は、この実施形態とは異なる適宜の順としても良い。例えば、前後移動台7上に左右移動台9を左右(X軸方向)移動自在に設置し、左右移動台9の上に上下移動台8を上下移動自在に設置しても良い。
In the above embodiment, the tool post 2 is annular, but the tool post 2 may be a polygonal ring such as a rectangle, or the hollow part may be circular and the outer peripheral part may be square. . Further, the tool post 2 may be divided into a plurality of parts in the circumferential direction, and there may be a gap between the divided tool rests.
The order in which the front and rear moving base 7, the vertical moving base 8, and the left and right moving base 9 constituting the movable spindle support base 16 are installed on the bed 1 may be an appropriate order different from this embodiment. For example, the left / right moving table 9 may be installed on the front / rear moving table 7 so as to be movable left and right (X-axis direction), and the up / down moving table 8 may be installed on the left / right moving table 9 so as to be movable up and down.

また、上記実施形態では、刃物台2を固定とし、主軸3の移動によって工具割出を行うようにしたが、刃物台2は中心軸回りの回転が不能なものであればよく、刃物台2と主軸3との間の直交3軸(X,Y,Z軸)方向の移動は、刃物台2と主軸3を支持する手段とに適宜分担させて行うようにしても良い。すなわち、刃物台・主軸相対移動手段4は、刃物台2および主軸3のいずれかを主軸軸心と平行な方向(Z軸方向)に移動させてワークWを刃物台2の中空部2に進入自在とすると共に、刃物台2または主軸3を主軸軸心O2に垂直な面内で移動させて刃物台2の複数の工具6のうちの任意の1つの工具6を選択でるものであれば良い。   In the above embodiment, the tool post 2 is fixed and the tool is indexed by the movement of the main shaft 3. However, the tool post 2 may be any tool as long as it cannot be rotated around the central axis. The movement in the direction of the three orthogonal axes (X, Y, Z axes) between the main shaft 3 and the main shaft 3 may be performed by appropriately sharing the tool post 2 and the means for supporting the main shaft 3. That is, the tool post / spindle relative movement means 4 moves either the tool post 2 or the spindle 3 in a direction parallel to the spindle axis (Z-axis direction) to enter the workpiece W into the hollow part 2 of the tool post 2. Any tool can be selected as long as the tool post 2 or the spindle 3 is moved in a plane perpendicular to the spindle axis O2 and any one of the plurality of tools 6 of the tool post 2 can be selected. .

例えば、刃物台・主軸相対移動手段4は、ベッド1に対して刃物台2を主軸軸心O2の方向(Z軸方向)に移動可能とし、可動主軸支持台16はX軸方向とY軸方向の移動だけを行うものとしても良い。また、主軸3を位置固定とし、刃物台2を直交3軸(X,Y,Z)軸方向に移動可能なものとして、刃物台2の移動によって工具6の選択を行わせるようにしても良い。   For example, the tool post / spindle relative movement means 4 can move the tool post 2 in the direction of the spindle axis O2 (Z axis direction) relative to the bed 1, and the movable spindle support base 16 is in the X axis direction and the Y axis direction. It is also possible to perform only the movement. In addition, the tool 6 may be selected by moving the tool rest 2 on the assumption that the main shaft 3 is fixed in position and the tool rest 2 is movable in the direction of three orthogonal axes (X, Y, Z). .
